Review Questions

• How do exchange rates influence trade balances in an open economy?
  • Exchange rates play a vital role in determining the competitiveness of a country's exports and imports. A weaker currency makes exports cheaper and imports more expensive, potentially improving a country's trade balance. Conversely, a stronger currency can lead to a trade deficit as domestic goods become more expensive for foreign buyers while imports become cheaper for domestic consumers.
• Discuss the relationship between capital mobility and economic stability in open economies.
  • Capital mobility can enhance economic growth by allowing for greater investment opportunities across borders. However, high capital mobility can also pose risks to economic stability, as sudden capital outflows can lead to financial crises. In an open economy, policymakers must balance the benefits of attracting foreign investment with the potential vulnerabilities that come from being exposed to global financial fluctuations.
• Evaluate the implications of the trilemma of international finance on open economy macroeconomic policies.
  • The trilemma of international finance states that a country cannot simultaneously maintain a fixed exchange rate, free capital movement, and an independent monetary policy. Open economy macroeconomic policies must navigate this trade-off; for example, if a country opts for a fixed exchange rate while allowing free capital flows, it sacrifices control over its monetary policy. This dynamic highlights the complexity of formulating effective policies that support both domestic economic objectives and global integration.
